Version history
Every published version of this article, newest first. Versions are append-only: a correction adds a row, it never rewrites history. Each version below states what changed against the version before it — which fields moved, and which body lines were added or removed.
The content hash is a SHA-256 fingerprint of that version's stored headline and body, computed when the version was written. Two versions with the same hash hold identical text; a changed hash proves the text moved. It is the tamper-evidence check — recompute it against an exported copy of a version and any silent edit shows up as a mismatch.
How we verify a hash — and how you can
Canonicalization: the hashed bytes are the version's stored headline, then the two characters ||, then the version's stored body markdown — UTF-8, SHA-256, lowercase hex. Nothing else is in the input: no normalization, re-wrapping or rendering is applied first, no trailing newline is added, and no other field (including the parent version's id) is mixed in.
Export a version's stored headline and body, join them with the two characters ||, and take the SHA-256 of the UTF-8 bytes. It must equal the hash printed beside that version. In a shell:
printf '%s' "HEADLINE||BODY" | shasum -a 256-
Version 4
Clarification
operator: removed a sentence about where the current status is shown. It described the article page, and the dek is the only prose in /feed.json — where there is no page. No fact about the road changed.
No change to the stored headline or body text was recorded for this version. (compared against version 3)

- > The following road construction project is in progress: grading adjacent to the roadway and paving adjacent to the roadway with delays 5 minutes, flaggers, lanes reduced to 2, no passing, speed limit 45 mph, traffic routed to opposing lanes, and width limit 11 ft until further notice. Hwy 50 Reconstruction is occurring from 1/2 mile west of Hwy 37 South east to the east edge of Tyndall. Two-way traffic will be maintained on 1/2 the roadway while the other half is constructed. The speed limit will be reduced to 45mph for the length of the project. A 11' wide width restriction we be enforced. The project will take all construction season long.

- **Road work: miscellaneous construction** is listed at SD-50 from 1 mile west to 2 miles east of Junction South Dakota 37 South-Tyndall, according to the South Dakota Department of Transportation's traveller-information feed.
- The feed publishes a listed start of 2026-04-07T20:11:00.000Z and no listed end — the feed publishes none for this record, which is how it represents work scheduled until further notice. Times are given in UTC as converted from the feed's own numeric timestamps.

- The feed publishes a listed start of April 7, 2026, 2:11 p.m. MDT / 3:11 p.m. CDT and no listed end — the feed publishes none for this record, which is how it represents work scheduled until further notice. The feed publishes those as numeric timestamps, so each is shown as a clock reading in both of South Dakota's zones — Mountain first, Central second. They are the same moment. The feed names a route and not a zone, so 605Buzz does not pick one for you.
